I certainly hope selling my car was not a big mistake, but I've done fine not using it for the past few weeks, and I can't think of any reason why I'd need to leave Seattle by car for the next year or so. I can always rent a Flexcar or a U-Haul if I need to. But I'm quite happy about the financial and environmental benefits of taking the bus. It's $44/quarter, which saves so very much gas, parking, registration, insurance, etc... Not to mention the whole global warming bit.
Okay time for class!
